OK, humour me. Please move those files to somewhere else (somewhere safe) like in your home folder.
Reboot and check again your logs. Is system-modules-load still complaining?
This is just so we can rule out if these files are trying to load some module that for an unknown reason has problems to load on boot.

EDIT: Do you get any output when you run sudo /usr/lib/systemd/systemd-modules-load ?
